Description

🚨 **IF THIS TOOL RETURNS A QUOTA ERROR:** - The error message will include a clickable upgrade link - Show the FULL error message to the user (it contains the upgrade link) - DO NOT attempt to work around the error or use alternative data - DO NOT create campaigns or perform actions without valid tool data - STOP and direct the user to upgrade via the provided link Replace the grouped audience on a Demand Gen (or YouTube) ad group. Demand Gen uses a single grouped audience per ad group — you cannot add one more segment to a live ad group, so this REPLACES the whole audience (removes the old one and builds a new grouped audience from the segment IDs you pass). ⚠️ Use `search_audiences` FIRST to find real audience IDs — NEVER fabricate IDs (wrong IDs target unrelated audiences and waste budget). **Accepts:** in_market_audience_ids, affinity_audience_ids, custom_audience_ids, user_list_ids. **Required:** ad_group_id + at least one audience ID. Only works on Demand Gen ad groups.
